It is the last week in Sweden for this time and Linköping is on our agenda. We needed to create a proper schedule to get everything together and be able to meet as many as possible this time. We were on a bitcoin meeting with our old friends Kalle and Magnus, as well as some new faces that we haven’t met before. Kalle has been very productive since we left Sweden and he has started a consulting firm in blockchain technology, and together with Rusty Russell, developed a proposal to use a technique called “Invertible Bloom Lookup Table” (IBLT) to reduce the size of the transaction blocks by not having to send the same transaction several times through the network that authenticates the transactions. This weekend Kalle and Rusty were invited speakers at the “Scaling Bitcoin”- conference in Hong Kong to discuss their proposals based on IBLT. This is so awesome and we hope that you visited his lecture if you were there!

We have worked a lot, so the first two days in Linköping was devoted to our computers, but then we could begin to meet up with friends and hang out with them! We have eaten a lot of dinners while talking about life and everything else, but also had time to listening to our friend Karin’s choir Chorus Lin, that performed an Advent concert in the S:t Lars Church in Linköping. We have also been past our old jobs and said hello to Cell Biology floor 11 and Medical Microbiology floor 12. We want to say a big thanks to all our friends that we managed to meet, it was incredibly exciting to see you for a moment! Thank you Linda for giving us a place to stay this week and for borrowing your wifi! I hope we can meet you all somewhere in the world!

Next, our journey continues and there will be a new continent to explore, but first celebrate Christmas in Mexico!
